RECORDING-PEN.

SPECIFICATION forming part of Letters Patent No. 768,473, dated August 28, 1904.

l Application filedv February 1,1904. Serial No. 121,462. (No model-l To all whom it may concern:

Be it known that I, COLEMAN J. MANNING,

of Medford, in the county of Middlesex and' the application of an excessive or irregular amount of ink to the recording-surface and 'without involving objectionable complication or delicacyof construction.

The invention also has for its object to enable the pen to be adjusted to any degree desired to regulate the flow of ink from it.

The invention also has for its object to enable the pen to be adjusted so that it will entirely prevent the iiow of ink when the pen is not in use. n

To these ends the invention consists inthe Iimprovements which I will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification, Figure l represents a side elevation of a recording-pen embodying my invention, the pen being' shown engaged with a holder. Fig. 2 represents an end view of the pen looking toward its ink-delivering end. Fig. 3 represents a section on line 3 3 of Fig. 2. Fig. 4 represents a sectional view of the casing 0r outer member of the pen shownin Fig. 3. Fig. 5 represents a side elevation of the inner member shown in Fig. 3. Fig. 6 represents a section on line 6 6 of Fig. 5. Fig. 7 represents a view similar to Fig. 3, showing a different adjustment of the inner member. Fig.8 represents a section on line 8 -8 of Fig. 1 looking downwardly. Fig. 9 represents a plan View of the pen holder or carrier detached from the pen. Fig. 10 represents a view similar to Fig. 2, showing a modification. Figs. 11 to 15, inclusive, represent sectional views showing other modifications.

The same reference characters indicate the 5o same parts in all' the figures.

Referring first to the `preferred embodiment of my invention shown in Figs. 1 to 8, inclusive, t' and ZJ represent the members ofv my improved pen. The outer member a, which incloses the inner member'b, is tubular and is provided with a contracted or frusto-conical lower portion a', in the center of which is a circular opening a2. The inner member b is provided with a substantially conical marking-tip 6o which projects partially through the opening 0:2. The inner member is also provided with a longitudinal slot b2, which intersects the apex of the tip b and is of suiiicient length to enable the parts of the member b separated by the slot to be moved toward each other, and thus vary the Width of the slot, the resilience of the said parts' causing them to normally stand with the slot open or at its maximum width.

Means are provided for causing a longitudinal movement of one of the members relatively to the other to vary the extent of projection of the marking-tip e' through the opening a2, said means in this embodiment of my invention being an external screwthread Z13, formed on the inner member b, and an internalscrew-thread a3, formed in the outer member a and engaging the thread b3. The upper end of the member I) may be slotted `at to engage a screwdriver.; It will be seen lthat when the member bis rotated it will be given a longitudinal movement in the member (t and that when this movement is such as to increase the proy jection of the tip b' through the opening a2 the parts of the tip will be forced inwardly by the contracted portion a' of the outer mem-I ber, thus decreasing the width of thc slot, as indicated in Fig. 7, and correspondingly de` creasing the How of ink through said slot, the

slot communicating, as hereinafter described,

with an ink-reservoir. I have found that the substantially conical tip b', having a slot intersecting the apex of the tip and communieating with an ink-reservoir, constitutes a very desirable and effective marking device adapted to move smoothlyin any direction K over a recording-sheet without scratching or vll . the recording mark or line to be varied, yas `may be found desirable, The said provision for adjustment also permits compensation for variations in the fluidity ofthe ink or marking agent employed. The compression of the marking-tip to decrease the width of the slot may be carried to such an extent as to close the slot and lprevent the passage of ink therethrough when the pen is not in use. be seen that the construction of the member is in some respects like that of a draftsmans ruling-pen. It differs, however, from the ordinary ruling-pen in that the'markingtip is substantially conical and canbe moved in any direction without affecting the result or the character of the line-that is to say, the movement of the pen may be in a direction at right angles to the plane of the slot a2 or it may be parallel with said plane. In this embodiment of my invention the inner member is tubular, its internal cavity b* constituting an ink-chamber. The outer member a covers the slot 62 and prevents the escape of ink therethrough excepting at the part f of the tip which projects belowthe opening a2. c represents a cap or cover which is applied to the upper end of the outer member a and prevents the evaporation of 1 ink. The said cover has a flange e', which may have a frictional or a screw-thread engagement with the member a.

d represents va holder for the above-described pen, the said holder being an arm adapted for connection at one end with'a suitable support and having at its opposite end a circular orifice d', adapted to receive the outer member a.y Said member is provided with peripheral fianges a5 as, the lower one of which is seated on the portion of the arm d surrounding thelorifice d.

d2 represents a` hook-shaped arm pivoted flat da to the arm d and having a hook d* adapted to enter the groove between the fianges a5, and thus hold the pen in engagement with the arm d. v

In Figs. 10 to 15, inclusive, Ishow Various modifications, all embodying the essential features of my invention; .These modifications will be next described. Fig.y 10 shows the inner member b provided' with two slots. b2,

each intersecting the apex of the marking-tip b', so that the said tip is subdivided into four sections or nibs instead of'two, as in the construction shown in the figures previously -referred to. InvFig. 11 I show the upper end portionfof the member b extended and provided with a flange 65 and with a cap 6. -In

It will -nib a, which cooperates withthe nib 67.

out an ink-chamber, the diameter ot' said member being reduced, so that an angular inkchamber g is formed between it and the member a. In this case the internal thread engaging the-external thread on the member b is formed ina cap L, detachably engaged with the member a. In Fig. 13 the inner member instead of having a plurality of nibs separated bya slot has a single nib 57, which constitutes practically half of the cone-shaped tip shown in the preceding figures. The contracted lower end of the outer member a is in this case extended downwardly at one side of said member to form a compleme al t the other side of the nib [J7 from the tapering vlportion a is a shortertapering portion a7,

which bears on the outer surface of the nib 127 and causes it to move toward the fixed nib a when the member bis moved downward.

In this case one side of the ink-delivering slot is formed by a portion of the outer member and the other side by a portion of the inner member. case by an adjusting-sleeve s, which is internally screw-threaded to engage an external thread on the member b and is rotatively engaged with a flanged nut-s', engaged with the outer member a. The rotation of the sleeve 8' causes the member b to move endwise with- The member b is adjusted in this out rotating;4 In Fig. 14 I show an inner member bs, which is considerably shorter than the inner member shown in the preceding figures, its inner end being seated on a shoulder a8, formed on the interior of the outer member a. In this case the outer member a has a contracted lower end portion a, which is made in a separate piece adjustably-connected with the lower end of the body por-,- tion of the member a by screw-threads.l InV this case the Variation of the width of the `slot b2, is effected by adjusting the contracted portion a". In Fig. 15 the inner member b is engaged withv a cap 67, which is engaged with the body a and hasy an orifice closed by a plug 1". f
